Samba provides file and printer sharing services to SMB/CIFS clients.
A denial of service flaw was found in Samba's smbd daemon process. An authenticated user could send a specially crafted request which would cause a smbd child process to enter an infinite loop condition. By opening multiple CIFS sessions, an attacker could exhaust system resources (CVE-2007-0452).
Users of Samba should update to these packages, which contain a backported patch to correct this issue.
